Simple carbs, also known as simple sugars, provide the body with instant energy. The body quickly digests and absorbs them. They are found in anything from refined sugar and sweets to fruits and dairy products. Some simple carbs have absolutely no nutritional value and they tend to increase the fat levels in the body.
Complex carbs, take a longer time to digest and release energy at a slower pace. They are the fuel for the body. Complex foods (unprocessed ones) are rich in minerals, fibres and vitamins.
